Clean Flexibility Roadmap sets out plan to put consumers at the heart of our future energy system

23 July 2025 - RenewableUK press release

Commenting on the publication of the Clean Flexibility Roadmap by the Department for Energy Security and Net Zero (DESNZ), Ofgem and the National Energy System Operator (NESO), RenewableUK's Director of Future Electricity Systems Barnaby Wharton said:

"A secure, affordable and resilient power system based on renewables needs flexibility at its core, to match times when wind and solar are generating with smart demand.

"This Roadmap puts consumers at the heart of that system, empowering households and businesses to take control of how and when they use electricity, so they can save money by using power when it’s cheapest.

“By embracing smart tariffs and technologies like EVs, modern heating systems and home batteries, and by accelerating the rollout of more grid-scale batteries and Long Duration Energy Storage alongside renewables, we can build a more agile system which can shift, adapt and respond to demand faster. Scaling up our capacity to store energy is essential to strengthen the grid and enhance the UK's energy security.

“To achieve this, the Roadmap recognises the importance of opening energy markets to flexibility service providers by removing barriers and improving price signals. For example , it pledges to explore the use of blended finance (public and private investment) to develop Long Duration Energy Storage projects. We welcome the commitment to ensure there is an attractive investment environment for grid-scale battery storage, as this is needed to reach the Government’s target of clean power by 2030.

“We also welcome the commitment to work closer with the EU to improve electricity interconnector trading arrangements, as this will further strengthen the the resilience of our clean energy system.

“This won’t only benefit billpayers, as we also have an opportunity to grow new supply chains manufacturing batteries in the UK, and to create highly-skilled jobs, in part by ensuring that training is available in this cutting-edge technology. We are keen to work with the Government to maximise these benefits so that we can foster significant economic growth in the years ahead”.
